This invention relates to a device .for guid in the rubber feed between the rolls of. a ru ber sheeting or coating calender. It has for its-object the improvement. of

guidesof this character in providing for rapi replace-- ment ofworn out parts, permitting the accurate adjustment vof the different compoguide, and makingpossible the' theparts rapidly and Without the use of tools.

Referring to the' drawings,

Fig. 1 is a partial section through a stand..

ard form of calender to lwhich my improved guide has been applied;

Fig. 2 is a side elevation of the'parts shown in. Fig. 1';

Fig. 3 isa section'on Fig. 4 is a section corresponding lto Fig.

i l, but with the rubber feed removed an parts of the guidebroken away; and- Fig. 5 is a section on line 5--5 of Fig. 2;

I have shown the device'as applied to a calender of a conventional construction com'- prising rolls 10,- 11, and 12, mounted in a frame 13; Suitable inechanism'for driving the rolls is supplied in al standard manner which it isv not necessary to illustrate.. Be-

tween rolls 10 and 11 is laced the feed of rubber 14 which is sheete lout` by vthe action of these rolls and by the action f rolls 11 .and 12 into the sheet :15. n order to keep the feed 14 from overrunning at the ends of the rollsand to keep it within the width feed a so-called calender guide. It is to the 'construction ofthis guide that my invention desired for the sheets tobe. manufactured, it isnecessary to apply at each end of the relates.

Mounted-at each end ofthe calenderframe 13 is a rotatable rod or post l'having a flattened portion 17.V A block 18 is 'secured to each rod by a set screw 19 acting upon the flattened portion of the rod. A .frame 20 is guided upon the block by ways .21A so that it may be moved toward orffroxn-they calender roll. A screw- 22 having ahandvrwheel 23 is held against axial movement in the block by a pin 24a' fitting into a groove 25 at one end of the screw. Intermediate its length this screw 'is threaded into the frame 20, so that byjf rotating the handwheel the frame may be'moved toward or away from the calender roll.

Slots- 26 inthe frame '.providefor themonting of a wedge-shaped blockor guidf .of rolls 10 and 11.

guiding piece 27.

.20' can "be moved awa in any desired position of adjustment while l permitting a slight relativefree motion of the parts. In order to vary this'adjustment screws 29are threaded into the frame 20 and 65 are held in adjusted position by lock nuts 30, the Vends 'pf thejscrews bearing against plates 31 securedto the Set below the guiding 32 bearing agwooden support-33 which lin turn carries an {aluminumshoe .34fshap'e'd l.; to the curvature v{f f roll 11 and adaptedl to be pressed into close contact with it. indicated in Fig. v2, this shoe is 'set at a slight '(5' angle in order to act asa plow and to turnv back the marginaly portion 40 of rubber which remainson the roll 11 vafter the sheet 15 has been trimmed ,to the desired Width.fv .This bracket is held to the frame by arbolt v35 passing through a hole in the bracket .and loosely through a slot 36 in the frame. A screw 37 held by lock nut-38 to the frame 20 bears against the bracket in order` t`o afford means of varying the adjustment of the shoe 3.4 relative to the roll' 11, the shoe having a slight free motionbecauseof the loose fit of bolt 35 in slot 36. While the calender. is in operation my improved guide functions in substantially the 90 same mannerl as guides lnow in use. When 1t is, desired to remove the guidetemporarilyeither for cleaning the calender or for other purposes, the improvements which I have incorporated become apparent. If it is desired to backwof the4 guide slightl for the sake of cleaning the calender the rame from the calender roll', carryingA the gui e piece 27 and the shoe 34 with it, by turning the handwheel 100 23. The adjustments of the uideV piece and 'fthe shoe'are not affected by t is backing off,

'awery important 4distinction over prior devices. In some cases, also, 1t may be desu'- able topl'ace guides on each side of the cal- 105 ,ender sol that the latter can he run ineither direction. ,The construction described lends itself perfectly to vthis arrangement, as.'l the `calenderoperator can back off the inactive guides by turning handwheels 23 without llo the 60 louter face of the piece-27 is afbracket 7() .changing the relative adjustment of the piece 27 and the shoe 34.

, If it is desired to change the facing on the shoe 34 the construction of my improved guide permits a ready removal of this shoe without disturbing the .adjustment of the guidepiece 27. Furthermore if it is desiredsheeted out by the calender the rolls 10 and .1l must be'varied-in their separation one from another. The slightly loose mounting of the block' 27 and` the shoe 34 by means `of bolts 28 and 35 respectively; and the pivotal movement of the entire guide upon the calender frame through the post 17 permits the when the handwheel 23 Iis turned up to press the parts against the rolls. In prior guides a change in the separation of the rolls necessitated a complete change in thev independent adjustments of the guidingelements,

.whereas with -my guide the necessary cor rections take -place almost automatically.

Having thus describedmy invention, I clai1n:' s

1; A calender guide having a block provided' with ways, means 'piece7 guides' vto seek' a proper' realignment for supporting the block in adjusted position adjacent the calender rolls, a frame movable in the Ways towards and Jfrom the calender rolls, a guide piece sha'ped to fit between the calender rolls,

means for holding the guide piece in adjusted position on the frame, a shoe shaped to bear against one of the calender rolls,

' means for holding the shoe in adjusted position on the frame independently of the guide and means for holding the frame in adjusted position in the -ways without disturbing the adjustment of the guide piece and shoe on'the frame.

2. A calender guide comprising a frame adjustablev towards and away from the calender rolls,` a' guide rpiece shaped to iit between the vcalender rolls and adjustably mounted on the frame`and a shoe shaped to bear against one of the calender rolls and adjustably mounted in the frame independl ently of the guide piece.

3.l A calender guide comprising a pivote'd frame ad'ustable towards and away from the calen er rolls; a guide piece shaped to fit between the calender rolls, adjustably mounted on the frame, and having a slight free movement thereonand a shoe shaped to bear against one ofthe calender rolls,v

adjustably mounted in the' frame independently of theY guide piece,

mil

and haying a slight t reemovement with respect to the frame.
